I've got Visio Professional 2007 and am trying to
reverse-engineer sybase schemas. The Microsoft URL's for
Visio says Sybase has been removed from the database
modeling solutions in Visio Pro 2007. However, they also say
I can use generic ODBC and generic OLEDB drivers to do this.
I can't figure out how to do it.

Does anyone have a step-by-step procedure for this? I've
already got all the Sybase client software installed.
